C6 appears to be a 0.1uF ceramic capacitor.

That cap has a polarity marking and it looks like an electrolytic.

Just checked the service manual and it is a 10 uf tantalum. (page 115)

They will blow up when they short. you should be able to replace

it with a regular electrolytic.

Look at C4, C5 and C7 to see what you need to replace it with as they’re the same.

It appears that the circuit uses the caps to smooth the movement from the potentiometer.

Not sure why that’s blown…

thanks, the others have 106 +25 on them so I’ll get some and give it a go, thanks
